    "abstract": "We consider a chain described by a next-nearest-neighbor hopping combined\nwith a nearest-neighbor spin flip. In two dimensions this three-body term\narises from a mapping of the three-band Hubbard model for CuO$_2$ planes to a\ngeneralized $t-J$ model and for large O-O hopping favors resonance-valence-bond\nsuperconductivity of predominantly $d$-wave symmetry. Solving the ground state\nand low-energy excitations by analytical and numerical methods we find that the\nchain is a Luther-Emery liquid with correlation exponent $K_{\\rho} =\n(2-n)^2/2$, where $n$ is the particle density.",
